Just Wondering

First let me say I am a 66 year old single man, divorced over ten years ago. I did try the dating scene for a short while and there was way too much drama and Women around my age want companionship and not sex. I live alone way out in the country and sometimes I admit I get very lonely. Over time I started wondering about trying things with another man, the thought came and went and it wasn't long until I was thinking about it constantly. I found a site and didn't realize there were so many men looking for another man for oral sex. I read the ads over and over for quite some time then one night after a few glasses of wine I answered one of them. We chatted then exchanged phone numbers and agreed to meet. I made sure he knew I was not a pro and this would be my first time and he was perfectly fine with that, So we met and actually hit it off which made me feel more comfortable and we drank our coffee and headed back to his place. Along the way I was so nervous but also very excited at the same time. I have to add that his place was beautiful and when we went inside he told me to make myself at home and he went into his bedroom and came back wearing only a robe. He politely asked if I still wanted to do this and I quickly said yes and reminded him this was my first time. He became a coach at that very moment taking his time and telling me what to do. He sat back on the couch and opened his bathrobe and told me to kneel on the carpet in front of him. He told me to kiss his cock which was getting hard, which I did, then to lick around it and up and down and then it happened..........I felt another man's cock part my lips and go into my mouth. I won't lie the feeling was so new and unbelievable and soon he was holding my head and rocking his hips up and down and then it happened! He groaned and in a second without warning he started to cum in my mouth and not sure what I should do I swallowed. I just stayed on my knees until we both caught our breath and he went into the bathroom and I went into the kitchen to get a napkin to wipe off my mouth. He came back and said I did great for the first time and oddly enough I felt good hearing that. I left after he said he would be in touch and on the way home while driving I realized I was now a cocksucker. I'm wondering if other men have though about doing the same thing or already have?
